主权项 1. An apparatus comprising: a touch sensor comprising: a plurality of drive lines; anda plurality of sense lines each adapted to capacitively couple to one or more of the plurality of drive lines; and one or more computer-readable non-transitory storage media coupled to the touch sensor and embodying logic that is configured when executed to: drive, at a first time, first and second drive lines of the plurality of drive lines, each with one or more electrical pulses, the first and second drive lines being adjacent to one another; anddrive, at a second time and without driving the first drive line with one or more electrical pulses, the second drive line and a third drive line of the plurality of drive lines, each with one or more electrical pulses, the second and third drive lines being adjacent to one another.
